Read the passage excerpt:
'Rewilding represents a conservation strategy aimed at restoring trophic complexity and ecological self-sustainability through the reintroduction of extirpated apex predators and ecosystem engineers. By reinstating top-down trophic cascades, predators regulate excessive herbivore browsing pressure, which in turn facilitates the regenerative resurgence of riparian woodlands, stabilizes riverbank geomorphology, and bolsters freshwater biodiversity.'
What primary objective defines the rewilding conservation approach?
Answer and explanation
Correct answer: A. Restoring self-sustaining ecosystems and trophic complexity through species reintroduction
- Step 1: The passage defines rewilding as a strategy 'aimed at restoring trophic complexity and ecological self-sustainability through the reintroduction of extirpated apex predators and ecosystem engineers'.
- Step 2: The option 'Restoring self-sustaining ecosystems and trophic complexity through species reintroduction' directly reflects this definition.
Answer
Restoring self-sustaining ecosystems and trophic complexity through species reintroduction.
Why not the others: 'Fencing wild animal species permanently inside captive safari reserves' describes captive management, not rewilding; 'Clearing indigenous woodlands...' is the opposite of environmental restoration; 'Culling apex predator populations...' is directly contrary to predator reintroduction.
